This map shows the percent of total renewable water resources dependency ratio or originating outside the country.

What is Dependency ratio?

Dependency ratio may theoretically vary between 0% and 100%. A country with a dependency ratio equal to 0% does not receive any water from neighbouring countries. A country with a dependency ratio equal to 100% receives all its renewable water from upstream countries, without producing any of its own. This indicator does not consider the possible allocation of water to downstream countries.
